A/N: So. Here we are at chapter 10!  You've read this far, but now for some sad news: From now on, chapters will be uploaded once, maybe twice, a week (Most likely on a Sunday or Wednesday) as school has just started again.  I just hope that I can actually finish the story in the five months before the scheduled release of HPOOP, so the themes in this story can't be foiled.

Chapter X: Who?

Harry was still puzzled by the Uberty Ravenclaw puzzle, and before he knew it, one whole month had passed since the November the First Quidditch match, and there had since been no clues from Snape (Harry was relieved).  The best thing of all was that in three weeks, Harry would be away from Draco Malfoy for fourteen days!

It was one week before the Holidays started that Harry got another letter.

I can't make this letter long, just don't show it to Dumbledore, the reason isn't visible.

S. Snape

Harry touched the letter and muttered Revealo and as usual a message appeared. But not like usual, the invisible message did not contain initials. 

IMPOSTER! REAL AT AZKABAN.  TIE UP DUMBLEDORE FOR HOUR.

This could only mean one thing: Polyjuice Potion.

Harry wrote letters to Remeus and Sirius (Who were still in the boardroom)

Dumbledore's an impostor.  Tie him up for two hours.  Be with you soon.

From Harry.

Harry tied the letter to Hedwig, and let her out of the window.  Harry went to get Ron and Hermione up, and when he had, the three of them ran straight up to the Phoenix Boardroom with no one to be seen.  Harry went into the boardroom.  He saw a sight that he would usually dread seeing: Dumbledore tied up by Sirius Black and Remeus Lupin.  However, Harry noticed that Dumbledore looked much younger, and his hair was looking Darker than he'd ever seen it.

I hope my letter has reached him. Snape was desperate.  He was sure that the impostor had succeeded in leading Harry off the trail, and Voldemort would soon know that Snape himself was an impostor.

'SNAPE!' it was Malfoy.

            'Tell master that I am coming' Snape was becoming even more uncomfortable with that name every day.

            'Yes Snape.' Snape entered the chamber.  Voldemort was sitting, and he gave Serverus the most unusual request yet.

            'Go to Azkaban, and help guard our Detainee.'

            'Yes master.'

An hour later, Harry could notice that Dumbledore's face was becoming younger, and his hair was almost as dark as Snape's!

***

Snape arrived at Azkaban, and stood outside Dumbledore's cell.  Out of the next corridor, came two death eaters, who Snape could identify as Crabbe and Avery, and opened the cell next to Dumbledore's.  'In you go,' and before Snape knew what was going on, he was inside the cell.

***

The next hour, Albus Dumbledore was gone.  In his place was…

A/N: Sorry for producing the shortest chapter yet, but it was the best way to portray the story as it occurred.  So, now for our nice little traditional cliff-hanger chapter ending.

What will happen to Snape and the Real Dumbledore?  Who is the impostor?  How long has our impostor Dumbledore been in place?  Find out this time next week: Same Potty time, same Potty URL!
